I think it's a good idea.  I would have created one already, but the differences between Win32 and Posix named mutexes are fairly substantial, and I haven't spent the time to figure out how to hide the differences in a way that would make both camps happy.  It would be nice if it were possible to have a SharedCondition class that integrates with this as well, though that may turn out to be a tad tricky.

They don't exist in Tango.  I know because I created tango.core.sync, which is reflected in core.sync in druntime.
